After the assembly of the oscillator, connect the input voltage and keyer.
Current consumption is approx. 40mA @12.8V. You should be able to hear Q5 oscillator on your receiver.

Phase 2

Assembly of PA section

Current consumption is approx. 110mA @12.8V. (approx. 130 mA key down).
Should you wish to increase output power replace R7 with 220R. Under normal operation condition 2N3866 will get fairly hot - even while not transmitting. However this is quite acceptable - 2N2866 is robust transistor capable of 3W dissipation at 200C.

In order to improve the output spectrum of Genesis Q5 QRP transmitter it is strongly recommended to add a low-pass filter.
Described below is practical realization of two simple, yet effective LP filters:

-monoband version consisting of just two T50-2 toroids and
-four band version for 80m, 40m, 30m, and 20m (four T50-2 toroids)
